PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux

9       not be implemented on Linux.

NAME

12       pthread_self — get the calling thread ID
13

SYNOPSIS

15       #include <pthread.h>
16
17       pthread_t pthread_self(void);
18

DESCRIPTION

20       The pthread_self() function shall return the thread ID of  the  calling
21       thread.
22

RETURN VALUE

24       The  pthread_self()  function  shall always be successful and no return
25       value is reserved to indicate an error.
26

ERRORS

28       No errors are defined.

30       The following sections are informative.

EXAMPLES

33       None.
34

APPLICATION USAGE

36       None.
37

RATIONALE

39       The pthread_self() function provides a capability similar to  the  get‐
40       pid()  function  for  processes and the rationale is the same: the cre‐
41       ation call does not provide the thread ID to the created thread.
42

FUTURE DIRECTIONS

44       None.
